FDA Accepts NDA for Aldeyra's Reproxalap for the Treatment of Dry Eye Disease

Aldeyra Therapeutics announced that the FDA has accepted the new drug application (NDA) for topical ocular reproxalap, a first-in-class investigational new drug candidate for the treatment of the signs and symptoms of dry eye disease. The FDA assigned a Prescription Drug User Fee Act (PDUFA) date of November 23, 2023. The FDA noted that no potential filing review issues have been identified, and that an advisory committee meeting is not currently planned.
“NDA acceptance marks a critical regulatory milestone for Aldeyra as reproxalap continues to advance toward potential regulatory approval for the treatment of dry eye disease,” Todd C. Brady, MD, PhD, President and Chief Executive Officer of Aldeyra, said in a company news release. “Based on data from a number of late-stage clinical trials, we believe reproxalap has the potential to address the need for a rapid and durable ophthalmic therapy for the millions of dry eye disease patients who are dissatisfied with currently available therapies.”
Reproxalap is a first-in-class small-molecule modulator of RASP (reactive aldehyde species), which are elevated in ocular and systemic inflammatory disease. The mechanism of action of reproxalap has been supported by the demonstration of statistically significant and clinically relevant activity in multiple physiologically distinct late-phase clinical indications.
The NDA is supported by previously announced safety and efficacy results from five clinical trials encompassing data for ocular dryness symptom score, ocular redness, Schirmer test, and Schirmer test ≥10 mm responder analysis. The NDA includes activity ranging from within minutes of drug administration to up to 12 weeks of treatment, crossover and parallel-group clinical trial designs, and assessment in dry eye chamber challenge and natural environment settings. Topical ocular reproxalap has been studied in more than 2,000 patients with no observed clinically significant safety concerns; mild and transient instillation site irritation is the most commonly reported adverse event in clinical trials.
